ELECTBOJE'LATING APPARATUS Specification of Letters Patent.

Patented May 19, 190s.

To all whom it may concern:

Be it known that I, OHAnLns E. DE LONG, a cltizen of the United States,residing at Shreveport, in the parish of Oaddo and State of Louisiana,have invented certain new and useful Improvements in ElectrolatingApparatus; and I do declare the folowing to be a full, clear, and exact"descri tion of the invention, such as will enable others skilled in theart to which it appertainsto make and use the same, reference being hadto the accom anying drawings, and to the letters and gures of referencemarked thereon, which form a part of this specification.

My invention relates to an electroplating apparatus, and has for itsobject to provide an apparatus of that class which is simple andeconomical in construction and comprises the improved details ofstructure which will presently be fully described and pointed out inthe-claims.

In the accompanying drawings,-Figure I is a view in side elevation of anapparatus constructed according to my invention, the electrolyte tankbeing broken to show the parts contained therein. Fig. II is a top planview of same. Fig. 111 is a diagrammatic view of the generator circuit.

Referring more in detail to the parts,1 represents a base upon which acasing 2 containing a suitable generator is mounted; the generator shownin the drawings consisting of a series of dry cell batteries 3, althoughany suitable means for supplying an electrical current may besubstituted therefor.

On casing 2 is a suitable switch-board having the contact points 4, andconnected with said switch-boardis the negative pole 5 of the battery.

Adjacent to each of points 4 is an insignia indicating the metalrequiring the current strength furnished at that point. I

6 is a switch arm, which turns on a pin 7 and has a head 8 adapted forseparate contact with each of the switch-board points 4, and a handle 9,by Which it is manipulated.

10 is a contact head on which a number of cathode carrying wires 11 aremounted; the switch arm, and pin 7 being of conductive material and thepin and contact head being connected by a wire 12 so that a currentmaypass from the switch-board, through the switch arm, pivot pin,connecting wire 12, head 10, and wires 11 to the cathodes 13, which arecarried onwires -11.

Removably mounted in lugs 14 on case 2 is a bracket 14, which supports atank 15 containing a suitable electrolyte.

16 is a contact head with which the positive pole 17 of the battery isconnected.

The contact heads 10 and 16 are preferably looped as shown in Fig. 11,and a spring clamp 1016 mounted adjacent to the respective heads, andeach provided with a slot adapted to fit over said heads with atension'adapted, to lock the connecting wires thereto.

Attached to head 16 is a wire 23 connected with a suitable anode 18,which is submerged in the electrolyte in tank 15.

Base 1 projects beyond the ends of the casing to form supports forreceptacles 19 contaming ingredients for the various electrolytes, and20 are bands for holding receptacles 19' on their supports.

Covering casing 2 is a removable lid 21, provided with a handle 22, bywhich the entire apparatus may be carried.

When in use, the tank 15 is charged with a solution containing salts ofthe metal with which it is desired to plate the cathode, and

an anode of the metal from which the plating is to be made is attachedto wire 23, and sus pended in the electrolyte. One or more of thearticles which it is desired to plate are then attached to wires 11, andlikewise suspended in the electrolyte.

The switch arm is then turned to the contact point indicating thenecessary strength for decomposing the particular metallic salt used inthe solution, the current passing through the solution between the twopoles represented by the anode and cathode caus ing a covering of themetal carried in the solution to adhere to the cathodes, the processusedwith m apparatus being the ordinary process, well own in the art.

When the apparatus is not in use, the tank may be removed, and the wires11 and 23 and bracket 14 may be detached and placed in the case, theparts being easily and quickly assembled when desired.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent is 1 1. An electroplating apparatuscomprising a case, a battery in sa1d case, a switch board connected withsaid battery and having ourfor movement 1n conductive relation to saidswitch board, and anode and cathode con necting means leading one to thebatteryand one to the switch arm, forth.

2. An electroplating apparatus comprising a case, a battery in saidcase, means on sai case for supporting a solution tank, contact pointsconnected with said battery and exposed to the exterior of said case,anode and cathode connections, and a switch arm in conductive relationto the cathode connections, and adapted for contact with said contactpoints, for the purpose set forth. v

3 An electroplating apparatus comprising a case, bracket on the-exteriorof said case, a solution tank supported by said bracket, an anode insaid tank connected with said battery,

contact points connected with said battery.

and indicating current strength for wor with diiierent solutions, acontact head, cathode carrying wires connected with said for the purposeset connectin a battery in said case, a removable seams head, and aswitch arm connected with said head, and adapted for engagementwith saidcontact points.

4.'AI1 electro lating apparatus comprising a case having a ase extendedto form shelves atthe ends of the case, a removable top on said case, abattery contained within said case,

a switch-board connected With one pole of saidbattery and having contactpoints on the exterior of the case, a switch arm adapted for engagementwith said points, contact heads on said case, one of said heads beingconnected with said battery and the other with said switch arm, anodeand cathode wires carried by said contact heads, an spring clamps havingslots adapted to embrace said contact heads, all substantially as andfor the u ose setlforth.v

In testimony whereof my signature in presence of two witnesses. r

CHARLES E. DE LONG.
